BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 664,094, dated December 18, 1900.

Application filed October 6, 1899. Serial No. 732,767. (No model.)

To a/ZZ wle/0m, it may concern:

Be it known that I, AUSBORN F. OLD, of the city, county, and State of New York, have invented an Im provementin B`edsteads,of which the following is a specification.

My invention has reference to folding bedsteads; and it consists oflcertain improvements set out in the following specification and shown in the accompanying drawings, which form a part thereof.

Myirnprovements have particularreference to that class of folding bedsteads in which the extended portion has a capacity for telescoping prior to being turned into a vertical position. My improvements are directed to certain features of construction in a bedstead of this class, and more particularly to means for causing both the side rails of the telescopic portion of the bed to travel at the same'speeds when condensing the bed prior to folding it, which will be' better understood by reference to the drawings, in which- Figure l is a sectional longitudinal elevation of my improved bedstead. Fig. 2 is a plan view of same. Fig. 3 is an enlarged plan view of the gearing at one side of the bed, and Fig. 4. is an elevation of Fig. 3 with a portion in section.

A is the main pedestal portion of the bedstead and stand upon the floor.

B is the main folding portion and is pivoted to a pedestal portion by the pivots e, working in horizontal guideways E in the pedestal. The end portion next to the headboard is counterweighted, as at F, and provided near the upper part with guide-rollers G, working in vertical guideways H. By means of these guiding devices the folding portion B in turning to a vertical position is moved outward slightly and then inward.

C designates two side rails which are adapted to telescope with the folding portion B. These side rails are connected at their outer end with a footboard D,`which may be rigidly or otherwise connected. To the under side of each of the said rails C C are secured racks I, which rest upon gears J, secured to a transverse shaft T. It will be understood that by thus connecting the racks on each side of the bed any pressure applied to either one of the rails to telescope it into the folding part B will cause the other side rail to be drawn forward'to telescope it also. This prevents any possibility of binding and enables the bed to be easily telescoped and folded. The shaft T is journaled in a bearing K, secured to the outer end of the folding part B, and which bearings are also provided with upright guiderollers M, which work against the inner surfaces of the side rails. These rollers M hold the two side rails apart and also greatly reduce the friction due to their being moved. L represents stops secured upon the under side and free ends of the side rails and are adapted to come into contact with the gears J to limit the outward movement of the side rails and also stop the rotation of the gears and shaft, so that both side rails can only be withdrawn to the exact same distance.

I do not conne myself to the minor details of construction, as they may be modified or varied Without departing from the principles of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is l. In a telescoping bedstead, the combination of the base or pedestal part, the pivoted folding part pivoted to the base or pedestal part, the telescoping part formed with side rails guided upon the folding part, a rack secured to each of the side rails of the telescoping part, pinions meshing at all times with the racks, a loose transverse shaft of shorter length than the Width of the pedestal part connecting the pinions and carried by the folding part of the bedstead in bearings located upon the said folding part, guides carried by the pivoted portion and against which the inner faces of the side rails are guided, and stops to limit the extension of the side rails on the pivoted portion whereby the racks shall not leave the pinions or the side rails the guides.

2. In a telescoping bedstead, the combination of the folding part, the telescopiug part formed with side rails guided upon the folding part, a rack secured to each of the side rails, pinions meshing with the racks, a transverse shaft connecting the pinions and carried by the folding part of the bedstead, and upright guide-rollers journaled upon the fold- IOO ing part of the bedstead and adapted to aot upon the inner faces of the side rails adjacent to the gears.

3. In a teleseoping bedstead, the combination of the folding part, the teleseoping part formed with side rails guided upon the folding part, a dat perforated metal rack secured to the u nder side of each of the side rails, pinions meshing with the racks, a transverse shaft connecting the pinions and carried by the folding part of the bedstead, upright guide-rollers journaled upon the folding part of the bedstead and adapted to aet upon the inner faces of the side rails to hold the racks in alineinent with t-he gears, and bearings for holding both the shaft for the pinions and the upright guide-rollers.

4. In a telesooping bedstead, the combination of the folding part, the telesooping part formed with side rails guided upon the folding part, a rack formed of fiat perforated met-al secured to the bottom of each of the side rails, pinions of less width than the racks meshing with the said racks, a transverse shaft connecting the pinions and carried by the folding part of the bedstead, and downwardly-extendingstops on the ends of the side rails projecting below the racks for locking the gears and their shaft against rotation While still in mesh With the racks and after the side rails have been fully extended.

In testimony of which invention I have hereunto set my hand.

AUSBORN F. OLD.
